. 7'Clainis. My invention. relates to. improvementsin drink mixing and dispensing devices of. thecharacter disclosed inPatent No. 1,810,554issued to me June 16; 1931, in which adispenserfor powdered malted milk or other. comminuted material-and: a motor driven drink mixer are combinedin a. unitary structure. c l

An object of my present. invention is to provide a simple, attractive and efiicient device of. the m stantnature which requiresa minimum ofatime andeifort in the use thereof. p

More specifically it is an 'objectoff my. invention to provide holding means for the mixing receptacle which supports said' receptacle in protected position of; disuse; as well" as inv operative position and which, in the latter positionof said receptacle, serves to maintain. electrical contact between self-separating; switch elements electrically connected with. the mixing motor, but which, in the position of 'disuse of said receptacle orupon. removal thereof from. the device, permits of the separation of' said switchelements. Another object of the invention is: to supply a composite deviceof the present kindin which the a dispensing structure, at eachoperation thereof, discharges the comminuted materialin full-prede termined. measure and delivers such. charges into the miXingtreceptacle in the-variousipositions assumed thereby when supported throughsaid receptacle holding means. i l An additionalobject of" the invention is to combine a. mixing motor and dispenser in a unitary structure in such manner that the motor anddispenser each contribute in providing a closure for the mixing receptacle when it is supported-imposition of: disuse by the receptacle holding means. A further object of the invention is to provide in the dispensing structure, novel and effective agitating and feeding means cooperating toinsurethe delivery of the comminu'ted' material in full predetermined quantity;

With the foregoing and other objects in view, which will appear in the following "description, the invention resides in the novel combination and: arrangement of parts and in the details of construction hereinafter described and claimed.

Ref erence being had to .-the accompanying drawings in: which similar: reference characters. designate similar parts throughout.the1several'views, it will be noted that the illustrated. device includes a hollow standard A-havinga base Ill which 1'5 aifordsea: firm footing for the entire. structure. The front wallv |.I of'the standard A isconc'ave'in cross-section, the wall lz-2 forming the back and sidesof saidi standard being substantially semiicircular. At the top:of?the standard'A is an open top shell-like headsB including asbottom l3;in'.- tegral with the wall II! ofthe standard Aand also including a wall like-fiange Ill integral with said bottom. l3; the'interior of said. headbeingi in communication with. the interior of: the hollow standard; proper. Supported by-the standard A is a container C for malted milk orother com.- minuted. material to be added to ingredients .to be mixed' into drinks. 'I'hisicontairier. includes a lower partc having a cylindrical wall I5. and having. an integralibottom I6; which caps the shelllike head B of the standard proper andpover-e reaches the frontwall lilf thereof, said: lower part c of the container 0: being anchored in. place on said head B by means: of screws 11: (Fig. 5.) extending upwardly therethrough:andithreaded into the bottom Hi of thecontainer- This container C further includes a tubular body. l8-ztelescoped into said lowerpart c of the container; saidibody. being fitted with-a-removablecover l9: w The front of the lower partcof thecontainer C has a planiform face 20. A motor ZII'formed with a similar face #12-2:i at one side of the. shell thereof is supported through said; lower-part c of said'containen- Inmounting the motor 2| on said part cof the container, the face 22 of.- the former is brought. againstwthe face 202 of the latter, supportingstuds 23' (Fig. 2) issuing from the shell of the motor being fitted: into bores 24 in-- the container part c as shown in-FigL 2; .Removable locking pins 25 inserted intov vertical .bores- ZB' inthe container part. 0 pass through transverse bores in the studs: 23., the lower: ends of said pins-being threaded? into: the lower portions of-the bores 26 which are internally threaded to receive them. The lower face 21 of the motor shell is fiat and made flush with the lower face of the bottom I 6 of the container part c for a purpose soon to appear. 1 7

Depending from the vertically disposed shaft of the motor 2| is a mixer stem 28 having a mixer head 29 thereon. A cup-like receptacle 30 in which a drink is to be mixed is brought into the position shown in Fig. 2, wherein the mixer stem 28 is receivedwithin the receptacle 30 and the curved wall of said receptacle is received within the concavity in the front wall of the standard A. The ease with which the receptacle may be manipulated into and out of such-position will be readily apparent. To retain the receptacle 30 in its operative position as shown in solid lines in Fig. 2, I provide a holder therefor consisting of a pair of forwardly extending jaw-like arms 3|, 32 oppositely curved to receive said receptacle therebetween. These arms 3|, 32 are pivoted at their inner ends. in bearings 33 within the hollow standard A, the forward wall H of said standard being formedwith a slot 34 therein to receive said arms 3|, 32. Fingers 35, 36 on the arms 3 l, 32,.respectively, curve toward each other and overlap at their ends, the finger 35 occupying a position between finger 36 and the wall ll of the standard A. These fingers 35, 36 have elongated registering apertures in their overlapping portions and projecting through said apertures is a headed screw 31 which is threaded into the wall I 2 of the standard. I provide a U-shaped spring38 through the legs of which the'screw 31 also passes; This spring is interposed between the head of said screw 31 and the finger 36 of arm 32, and, exerting pressure against said'finger 36, normally holds the arms 3|, 32

in the position shown in Fig. 7 with the finger 36 of arm 32, abutting against the finger 35 of arm 3| and said latter finger in turn, abutting against the wall I 2 of the standard A.

' Said arms 3|, 32 are easily spread apart'against electrical energy to the motor 2 I.

the action of the U-shaped spring 38 to to receive the receptacle 3!], this operation being effected simply by using a finger piece 39 on arm 3| to swing the same outwardly. Upon such movement. of said arm 3|, its'finger 35, operating upon finger '36 of arm 32 and against the action of the spring 38, imparts an outward swinging movement to said arm 32. 'Thus moved outwardly in opposite directions the arms.3|, 32 are spread apart and the receptacle is easily passed open end foremost between said arms.

Upon releasing the arm 3| both arms 3|, 32 are swung toward each other by the spring 38, which acts against the finger 36 of arm 32, finger 36, in turn, acting against the finger 35 of arm 3|.

The diameter of the receptacle 30 is such that it is firmly gripped by the arms 3|, 32, before the finger 35 reaches its limit stop which is constituted, as above indicated, by the wall I2 of the standard A.

."Wires40 and 4| are employed in furnishing At corresponding ends, these wires 40, 4| are connected with a plug 42 (Fig. 3) secured in the base 0 at one side thereof, said plug having conductor prongs 43 extending outwardly from said base, said prongs being adapted to be received, in the usual manner in an electric socket member of conventional form. Said wires 40, 4| are threaded through the hollow standard A and connected with insulated spring terminals 44 (Fig. 8) situated in the head B of the standard A. A pair of conductors 45 (Fig. 2) running through the bottom of the container part 0 have terminals 46 at their inner ends contacting with the terminals 44 and also have terminals 41 at their outer ends which fit into an electric receptacle 48 (Fig. 2) built into the shell of the motor 2| for supplying current to the motor.

It being desirable that the motor 2| start and. remain in operation when the receptacle 30 is in its operative position (Fig. 2) and that said motor stop when said receptacle is removed from that position, I have devised means by which the circuit through the wires 40, 4| is automatically completed when the arms 3|, 32 are spread apart far enough to accommodate the receptacle in its operative position and by which said circuit is automatically interrupted when said arms are relatively nearer together. To accomplish this result a switch 49 (Figs. 7 and 8) is employed, the same being located within the head B of the standard C. This switch is cut-in the wire 40 and includes a body portion or block 50 of insulating material secured to the bottom |3 of the head B. Contacts 5| secured to the insulating, block 50 are connected with the ends of said Wire 40 where it is severed to permit of the interposition therein of the switch. Companion contacts 52, electrically connected, are carried on a crosshead 53 which, in turn, is carried on the legs of a U-shaped link 54, said legs of said link being slidably mounted in the body block 50 of the switch. An expansion spring is interposed between said body block 50 and said cross-head 53. Unrestrained, thisspring 55 slides the link 54 in the block 56 shifting the cross-head 53 away from said block and thus moving the contacts 52 from engagement with the contacts 5| on said block. Such action of said spring 55 is, however, countered by connecting the link 54 with the finger 36 of arm 32, said connection being made through the medium of an upstanding pin 56 caught at the upper end thereof within the bend of the link 54 and anchored at the lower end thereof on a lug 51 (Fig. 6) issuing from the finger 36. The action of the switch 49 in relation to the movement of the arms 3|, 32 may be readily understood upon inspection of Figs. 7 and 8. In Fig. 8, the arms 3|, 32 are held spread apart by the receptacle 30, in its operative position. With the arms 3|, 32 thus relatively disposed, the link 54 of the switch 49 is drawn against the action of the spring 55 sufiiciently to engage the contacts 52 with the contacts 5| and thereby complete the motor circuit. Any closing movement of the arms 3|, 32 as by the removal of the receptacle 30 therefrom or by the shifting of said receptacle upwardly into inoperative position while still in the embrace of said arms, will release the link 54 to the action of the spring 55 and said spring will retract the link, causing the contacts 52 to be disengaged from the contacts 5| (Fig. 7) and thus breaking the motor circuit.

As previously indicated, the lower face of the bottom l6 of the container C is flush with the lower face 21 of the shell of the motor 2|. This construction is devised to supply a fiat surface against which the lip of the receptacle 30 may abut when the receptacle is in the grasp of the arms 3|, 32. Under this arrangement, the receptacle 30 may be conveniently accommodated on the device itself and at the same time may be conveniently closed against the entry thereto of flies, dust or other foreign matter. A spring clip 58 may be secured to the lower face of the motor shell to engage the beaded lip of the receptacle 30 construction of which. is

and; aid; the; arms 3 ,..32;.ina holding: saith receptacle in its protected inoperative. position with the mouth thereof. closed by the. container C and motor 2|. I i

The receptaclatfl iso'f: the usual frusto-conical form. and: being in such. form permits the arms 31', 3.2.. to closer'upon each other sufficiently to? throw off the switch 49 when said receptacle'is thrust upwardly between. the arms 31, 32 from operative position as seen in solid lines; in Fig. 2 toprotected inoperative position, asseen in: Figs. 2* and 5; where-the mouth: of the receptacle is closed.

To prevent the lip of the receptacle 30 from catching in the slot 34 formed in thewall H of the. standard for the arms 3|, 32, I provide a closure plate 59 whichfits into the concavity of the wall H and overlaps said slot 34- except at the-ends thereof wherein the arms 3|, 32 play, asthey open and close.

Depending fromthe bottom |6 of the container part c is-a spout which directs thecomminuted material from said container into thei'eceptacle 3 0 heldin the grasp of the'arms 3|, 32. It is desirable that suchmaterial be dispensed in measured quantitiesand to that end I have incorporated within the container C a novel and effectivemechanism for so delivering material from said container. g

The lower part c of the container has a false bottom 6| spaced from the bottom proper US, said bottom proper having an orifice 62 therein registering with the spout 66 and sai'd'false bottom 6 l'having an orifice 63 (Fig. 9) therein offset from said first opening 62. Journaled concentrically in the bottom I6 and false bottom 6| of the container part c is an upright shaft 64' having an enlarged cylindrical portion or head 65, the lower end of which bears upon the upper surface of the false bottom 6|; Disposed within the space between'the bottom I6 and false bottom 6| is a measuring member D,v segmental" in form, the best seen in Fig. 12. This measuring member fits snugly between the bottoms |6 and 6| of? the container part c and includes an arcuate body 66 resembling a ring fragment. Integrally formed with the body 66 is a boss 6? having. a bore 68 concentric with the innersurface of the wall |15 of the container part c... Issuing radially outward from the body 66 intermediate. its ends is a pair of spaced blades 66, 6.9.. Formed integrally with the upper margins ofjthe blade 69 andbod'y 66 is an arcuate gate or closure l0- the same. extending from said blade 69 to the adjacent end of said body. Integrally formed withthe lower margin of'theblade 68 and the corresponding. margin of the body 66 is a second arcuate gate or closure 1 |'.which extends fromsaid blade, 68. to the adjacent. end of the body 66. The bore 68 inthe boss 6] receives the shaft 64 and a pin 12 passing. through said boss 61. and. shaft 64.1ocksf the measuring member D. to theshaft causing the one to turn with the other; The outer edges of the blades'68, 6.6 and arcuate. gates 16, H. skirt the wall. |5."ofthe container part. c.

Beneath the bottom I6 of the container is' asecond boss13 (Fig. 4) whiclriskeyedto the shaft M'by means ofa pin 14-. Formed'integrally with this: boss- 13 is an: actuating lever I6 having anfinger piece; 1.62 at the; outer endlthereofi. lever 1ft extendsrthrough. and; plays a: slot 11; (Eigsrl: and 2.). provided by forming, arecessn (it s..7 and;.8b. inthe upper edgeiof'jwallilflofithe head;B.of.theistandard.v Said wall |..at1the-forward extremity of: said. recess. 18:. constitutesastop 1 9; limiting: the forward. movement of said lever 16. and a. rubber bumper 8|l (Fig. 7;) anchored within said. head B supplies a: stop; limiting: the rearward. movement of the. lever. l5.

With the lever I 5 swung against the.ac-- tion: of the spring 8| into the position, againstthe. limit" stop 19, shownin. solid lines in. Fig; 9 and in dotted lines in Fig. 10, the pocket 11 of. the measuring member D. is situated in registry with the orifice: 62 in the bottom. 16 of the container; the gate I6. at such time closing the orifice 63in the false bottom 6 Thus, it. will be understood, that a dry granular or powdered material stored within the container C will gravitate through theorifice 63sin1the false bottom:.6i| anclifillLthe pocket d of themeasuringmember Dwhenthe actuating 1ever15' is in. its normal position. And, it will also be understood thatupon swinging: said lever I5 forwardly toits limit stop 19; the said: measuring pocket. (2 will be shifted into registration with the orifice 61 in the bottom l6, through. which: orifice the. contents. of said pocket will. gravitate and be directedby the spout 69 into the receptacle- 30 embraced by'the armsv 3|, 32. .The gate 1.61 closes the orifice 63 inthe false bottom 6|, when the measuring. member D occupies theabove described position. inwhich it releases its charge of material.

The comminut ed materials ordinarily dispensed in devicesof the present nature have a tendency to absorb moisture and thereby become more or less caked. It. istherefore desirable that means beiprovidedto minimize the caking of'the ma-- terials to be dispensed and that the filling of the measuring pocket (1'. with such material. be positively assured. Tothis end, I employ an agitator- E within the container C. In. the form: illustrated, theagitator includes. an upright stem 82f threaded. atits lower end into; the head.65 of the shaft; 64: Spaced arms 83, in. pairs,. at: right: angles to each other, pass through; and; are: sup;= ported by saidiagitator stem 82, the armsof each pair and the connecting reaches 84, joining; the ends thereof, consisting of a single piece-of wire. This agitator E oscillates upon the rocking of the shaft 64 and in so doing breaks its way through the material in the container with the result that any tendency of the. material. to cake is efiectively minimized. Cooperatingv with the agitator E in keeping the material to bedispensed in'powdered or granular form is a ratcheting spider'F. The principal functionof' said spider, however, is to feed the material into the orifice. 63 in the false bottom 6|; Said spiderFincludes a hub 85 journaledon the head of'the shaft 64", ,the-hub being formedwith radialblades 86- in edgewisecontactwith the upperface of the false-bottom 'tl. Ratchet teeth '87 formed peripherally of said=head 65,. are engaged by a pawl 88 (Fig. 11) slidable in a hollow stem, 89 issuing'from the hub 85, said pawl being yieldingly pressed into engagement with the ratchet teeth '81 by means of a spring 98 interposed between the outer end of said pawl 88 and a plug 9| threaded into the bore of said stem. Upon the spring, 8 I.

the dispensing throw of the lever'l5,.the spider F remains stationary, but upon the return throw of saidlever, when the pocket d in the measuring memberD is being retracted for a fresh charge of material, said spider F is turned through one of the ratchet teeth 81 and pawl 88 in a counterclockwise direction as seen in Fig. 9. The blades 86 of the spider receive material between them at the bottom of the container and shift such material a step at a time toward the orifice B3 in the false bottom 6!, the blade nearest to said orifice sweeping'the material ahead of it into said orifice upon each actuation of the spider F. Thus, until the contents of the container are practically exhausted, the spider F definitely assures the filling of the pocket d in the measuring member D assaid member is retracted for a new charge by As previously indicated, the pccketd is brought into registration with the orifice 62 in the container bottom E6 at the end of the operative throw of the measuring member VD. Thereupon the contents of said pocket gravitate through said orifice 62 and spout 69 into the receptacle 3!! embraced by the arms 3|, 32. This spout 68 and the mixer stem 28 are both enclosed by the receptacle 38 when it is positioned so that its lip abuts against the surface defined by the lower faces of the container C and motor 2|. It will be understood, therefore, that the spout 68 and mixer stem 28 are protected from contamination as well asthe interior of the receptacle, when said receptacle is pushed up against abutment surface provided to close the same in its position of disuse. 7

A counter 92 of conventional type is employed to record the number of charges of material dispensed from the container C. This counter is mounted within the head B of the standard and the readings therefrom are visiblie through a slot 93 (Fig. 4) in the wall M of said head. The counter actuating member, consisting of a reciprocating bar 94'is yieldingly projected into its extended. position by means of a spring 95.

Arranged to oppose the action of said spring 85,

by engagement with the extreme end of said reciprocating bar fllis a pin 96 (Fig. '10) which projects from the boss 73 on shaft 64. This pin 98 is so disposed radially of the boss 13 that it will strike and shift the bar 94lagainst the action of thespring 95 when the lever 75 is swung forward to deliver 1 a charge of material from the dispenserl- 'To simplify the electric wiring for a battery of my devices, provision is made for plugging one into another so that it is only necessary to conmeet the first of a'series of devices with the source of current. 'In the base iii of the standard, opposite the male plug 62 is a receptacle 9'! (Fig. 3) which 'will receive the prongs of the male plug of asecond devicel' This receptacle is'connected through wires 98 and 99 with the male plug 42 to which the wires 48, 4t are also connected, as

' previously described.
